Optical Access Network

A collection of access connections supported by an optical transmission system that are shared across the same network side interface. The optical access network may contain a number of optical distribution networks (ODN) and optical network units (ONU) connected to the same optical line terminal... Read More

ONU State and Activation Process of ONU

Initial-state (O1) The ONU in this state has just been powered on and is still in LOS / LOF. Once the downstream is received, the LOS and LOF eliminate, and the ONU moves to the standby state (O2). Standby-state (O2) The ONU in this state has been received to the downstream flow and is waiting fo... Read More
